GY6 Trans Cover Gasket (Short Case)

GY6 Transmission Cover Gasket for 125cc and 150cc Engines

This gasket suits short case GY6 engines in the 125cc to 150cc class. Its job is to keep the transmission cover sealed, which matters for stopping leaks and keeping the drivetrain running smoothly. If you handle your own scooter upkeep or repairs, it's one of the core GY6 scooter parts you'll want on hand.

Engine Code Compatibility

This gasket works with a range of engines built on the 157QMJ platform. Covered codes include 157QMJ, 161QMK, 152QMI, 1P61QMK, YN1P57QMJ, 1P52FMI, 154FMI, JJ157QMJ, 1P57QMJ, BN157QMJ, and BN161QMK-A. When your engine code contains "QM" or "FM," this gasket will most likely be a match.

Signs It's Time for a New Gasket

Swap out the transmission cover gasket when you spot leaking near the transmission area. Checking it regularly can catch seal problems before they grow. The best moment to fit a new one is whenever you're servicing the scooter or taking off the transmission cover.
